The GeoBulb® is most efficient when used in a ceiling or track lighting fixture. This is because most of the light is evenly distributed off the top half and sides of the bulb. The GeoBulb® is designed to minimize the light output toward the screw-in base of the bulb since this light is wasted for most uses. Many other LED bulbs point all of their light towards the top of the bulb which is less expensive to manufacture.

The GeoBulb is much easier and less expensive to install than a solar or wind generating system. The payback period should also be signifcantly lower since most solar systems have a payback period of 30 years.

Depending on which of the three colors you select, the GeoBulb® has a slightly different color than other light bulbs you may have seen before. Everyone is very sensitive to any color change in their lighting. I must say that getting used to a GeoBulb® is easier than getting accustomed to a compact fluorescent light. A GeoBulb® turns on without a delay and does not have a warm-up period. Here is a brief description of each color:

• Warm White is surprisingly close to the color of a normal incandescent bulb. It is likely that everyone who sees the bulb will assume it is an incandescent bulb. The light output is similar to a 40 Watt Incandescent bulb. This color is excellent for creating a warm lighting atmosphere.
• Soft White is a modern color similar to a halogen bulb. The light output is similar to a 50 Watt Incandescent bulb. It is suitable for a kitchen and general lighting.
• Cool White is has a slight blue hue and is most similar in color to daylight. The light output is similar to a 60 Watt Incandescent bulb. It is good for an office environment.

• Warm White is 2600 - 3000 Kelvin and close to a normal incandescent color.
• Soft White is 3600 - 4000 Kelvin and a modern color blend between Cool and Warm
• Cool White is 5,000 - 5200 Kelvin and has a slight blue hue but is close to actual daylight.

Cool White puts out the most light and is a good choice for work areas. Soft White has a pleasant color for general work or most home lighting. Warm White is for ambiance such as restaurant or home lighting.

The GeoBulb® is designed to be used indoors at an ambient temperature that does not exceed 95 degrees Fahrenheit. A ceiling downlilght fixture is an excellent application for the GeoBulb®. It also works well for desk lamps or floor lamps or any other open-type fixture.

The GeoBulb®-3 is rated to last up to 50,000 hours. This is over 5 years at 24/7 or approximately 34 years at an average use of 4 hours per day.

No, it is not recommended. Using the GeoBulb® with a dimmer may damage the bulb and voids the warranty.

The GeoBulb® will operate safely in a 3-way lamp controlled by a manual switch. You will not notice any difference in light output. It will be like operating a standard bulb (not a 3 way bulb). Touch sensor 3-way lamps are NOT SAFE to use the GeoBulb® in. The electronics in these lamps may damage the bulb beyond repair and will void the warranty.

The components and raw materials are expensive but LEDs do save a lot on energy. The up front cost is high for an LED bulb but it cost much more to run an incandescent bulb over a few years than an LED bulb. This is true for bulbs that are used often. The price of an LED bulb is beginning to meet the total cost to run a compact fluorescent when you include energy costs.

The Power Factor expresses the efficiency of the circuit. The GeoBulb® runs with a power factor of about .80, a CFL runs at about .50 and an incandescent runs at 1. To put it another way, you need a 60 watt generator for a 60 watt incandescent bulb, you need a 25 watt generator to run a 13 watt CFL and a 9.5 watt generator for the GeoBulb® To run a GeoBulb® the power company has to generate less than half the power required for a comparable CFL. It means the power company could reduce their generating capacity if we all switch to GeoBulbs® or any other energy efficient appliances.

There is another very technical reason the GeoBulb® is good for a power company. The circuit is a "leading" type which helps offset the type of power an electric motor requires - which is "trailing". The GeoBulb® helps balance the load delivered by a power company and can reduce the net power generated.
